IPT's mobile RO trailers did the impossible. They treated 250,000,000 gallons of high TDS, ultra high silica wastewater at nearly 60% recovery. Amazing stuff.
Mobile Reverse Osmosis
Integrated Process Technologies, Inc. (IPT) has recently completed sixteen months of 24/7 operation of two twin mobile reverse osmosis systems at a major coal-fired powerplant in eastern AZ treating a blend of cooling tower blowdown and stored evaporation pond wastewater. The conductivity/total dissolved solids (TDS) of these feedwaters ranged from 23,000 uS to 29,000 uS. The average dissolved silica concentration in the feedwater was 150 mg/L and a variety of other seasonal contamination (e.g. microbial, diatoms, brine shrimp, etc.,). RO recoveries ranged from 48 to 58% depending on the season of the year and average feedwater flow to each trailer was 320 gpm.
To download a two-page flyer of these mobile RO units, as well as other related general 'picture' drawings, please scroll down to the bottom and click on the 'Attachment' of interest.
Each of IPT's mobile RO units is housed inside 48-ft. refrigerated trailer and, depending upon feedwater quality, can produce up to 500,000 gallons per day of high quality permeate. A unique advantage of the design allows either mobile RO to be operated in the single pass or double pass RO configuration by making simple modifications to the concentrate flow connections.
Each trailer is equipped with its own built-in clean-in-place system, a variable frequency drive multi-stage feedwater pump, up to three chemical injection systems and two separate, internal prefiltration systems. Pressure vessel staging is such that membrane cleaning can be done for up to one half of the entire system without taking the other half off-line. All operator controls and instrument visuals are centrally located for easy control and convenient observation. A single 480 volt three-phase power connection is all that is required to operate all of the on-board systems.
There are three piping connections: feedwater, permeate, and reject. Recoveries as high as 80% or as low as 45% are feasible, again depending upon feedwater quality and temperature.

Sept. 2011 through Jan. 2012 IPT had one trailer on hot standby at a major powerplant in northwestern N.M.
